Hello, I have a problem after updating the system to Android 16. Before, everything was great. I have a custom application to work with ST25DV04KC. Now, the NFC service crashes before connection, and the system app opens NDEEF. Only on the first "tap...
We’re facing an issue with the ST25DV04KC tag. The tag is powered through energy harvesting. The GPO register unexpectedly resets to 00 whenever there’s a brief drop or interruption in the RF field or Communication. The GPO is configured to generate ...
Hello @all, I've downloaded ST25DVCryptoDemo for iOS from here, in order to take a look into the demo code for a new project.Once I've tried to build the Demo app I've got a big amount of errors. In fact the console gave me this message "too many err...
Dear ST Community,I hope you are doing great.I am having a trouble to run the GUI of ST25R3916 discovery board on my machine, I have windows 10 operating system, I tried to reinstall the included drivers (with the GUI), but the GUI is not able to re...
Hi. I recently started using set "NUCLEO-L476RG" and "NUCLEO-NFC08A1"..I launched the existing "NFC08A1_PollingTagDetect" project, which works via SPI, and everything worked fine.Then I decided to redesign the project for I2C. I ran into some problem...
Hello to the support community, i'm currently working on some custom coils used with the ST25R3916. I've studied the ISO/IEC 14443-2 for quite a while and recently had a look into the AppNote AN6065 from you guys. There is quite some confusion on t...
Hi. I bought a set of "NUCLEO-L476RG" and "NUCLEO-NFC08A1".The "X-CUBE-NFC6" library for the "NUCLEO-L476RG" contains examples of "NFC08A1_PollingTagDetect" and "NFC08A1_PollingTagDetectNDEF."How do I run them in the STM32 IDE?Which one should I use ...

Hi everyone,I'm working on a project where I need to read NFC tags from 4 different locations. To save costs and complexity, I'm considering using a single ST25R3916B and multiplexing it to 4 antennas.From what I've found, it's possible to use the di...
Hi everyone,I am working with the X-NUCLEO-NFC08A1, which uses the ST25R3916B chip, and I am planning to use it's main IC (ST25R3916B ) with 6 antennas. The idea is to use the two RF interfaces of the chip, with each interface connected to 3 antennas...
